TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 705,988, dated July 29,1902. Application filed April 5, 1901. Renewed December 30, 1901. SerialNo. 87,683. (No model.)

To (LZZ whom, it mag concern:

Be it known that I, HENRY M. WILLIS, a citizen of the United States,residing at East Williston, in the county of Nassau and State of NewYork, have invented certain new and useful Improvements inTobacco-Pipes; and

I do hereby declare that the following is a full,-

clear, and exact description of the same, reference being had to theaccompanying drawings, making a part of this specification, in which-'-Figure 1 is a central longitudinal sectional View of a tobacco-pipe madeaccording to my invention. Fig. 2 is an end view thereof. Fig. 3 is atransverse sectional view thereof, taken in the linea; ocof Fig. 1. Fig.4 is a detail View of one of the parts thereof.

This invention comprises certain new and useful combinations of partswhereby I am enabled to provide for clearing the bores of tobacco-pipesand for removing refuse materials from the bowls thereof with very greatfacility and convenience and without deformity of the pipes by reason ofknobs or projections extended therefrom.

Aisatobacco orsmokers pipe made according to my invention and which mayhave in a general way any suitable or approved contour -as, for example,that indicated in Figs. 1 and 2, which show a shape very common in pipesfor smoking tobacco, &c.

Formed in the bowl A of the pipe and axially,or practicallyso,coincident or in line with the tube or passage a of the stem Bthereof is a cylindric bore 1). Formed externally in the bowl contiguousto the outer end of said bore b is a cavity 0. In the bore b is placed aremovable plug 0, which has at its outer extremity an arm or lever cl,which is so shaped as to fit into the cavity a, with its outer surfacefiush, or substantially so, with the adjacent portion of the outersurface of the pipebowl A, as shown more fully in Fig. 1, there being,however, a space 6 between the edge of the arm or lever d and thecoincident edge of the cavity esufficient to permit the insertion of thethumb-nail or other thin instrumentality to longitudinally start theplug from the bore preparatory to the Withdrawal of the plug from thebore for a purpose herein presently explained.

Extended from theinner end of the plug 0 and fast thereto is a half-tubeor semicylindric scoop D, which is so placed and proportioned that whenthe plug is in position in the bore 17, as described, the scoop liesupon the bottom of the tube or tubular passage a of the pipe-stem B andto the extent of its circumference should be in contact with the wall orsurface of said tubular passage, so that by giving a turning or more orless rotary movement to the scoop the edge or edges of the latter arecaused to scrape the surfaces of the passage a. This causes all refuseor undesirable material adherent to said surfaces to be scraped off andcollected in the semicylindric interior of the scoop, so that it may beremoved bodily from the pipe by temporarily withdrawing the scoop fromthe latter. The pipe-stem B may be fitted with a mouthpiece f of anysuitable shape, and the several parts of the apparatus may be of anyapproved material. Thus, for example, the scoop may be, and preferablyis to be, formed of aluminium.

In the operation of the invention, the parts being in the relativepositions hereinbefore described and as shown in the drawings,when

the impurities and refuse substances which in the use of the pipe aredeposited in the passage a and in the lower part of the bowl Aaccumulate to an objectionable degree the plug 0 is withdrawn until itsarm d is clear of the cavity 0 and is free to turn without contact withthe outer surface of the bowl. The plug Ois then turned axially by alever-like action of the arm (1, with the result that the scoop isrotated and its edge is caused to scrape the inner and contiguoussurfaces of the pipe-passage a and to collect the scrapingst-hedebris-within the semicircular hollow of the scoop. The latter is thenwithdrawn by pulling out the plug, and consequently the scoop. The scoopbeing then emptied and replaced the pipe is ready for repeated use forsmoking and is in a condition free and clear from objectionableaccumulation or deposits in those portions of its interior in which suchaccumulations are mostobjectionable. Bythusprovidingabore in the outerside of the pipe-bowl opposite the passage in the pipe, with a removableplug in the bore, which carries a cleaning device,

the pipe may be readily kept clear of undesired deposits andaccumulations, and thereby kept in satisfactory condition for use.

What I claim as my invention is 1. In a tobacco-pipe, the combinationwith a bowl which has a cylindric bore axially coincident with the tubeor passage of the pipestem, and a cavity in its outer surface whichconnects with said bore, of a plug which is arranged to turn in saidbore, an arm which is provided to the outer end of said plug andarranged to lie in said cavity with its outer surface flush orsubstantially so with the contiguous external surface of the bowl, and asemicylindric scoop provided to the inner end of the plug, placed in thepassage of the pipestem and arranged to scrape the surface of saidpassage when turned by an axial movement of the plug, substantially asherein described.

2. Ina tobacco-pipe, the combination with a bowl which has a cylindricbore axially co incident with the tube or passage of the pipestem, and acavity in its outer surface which connects with said bore, of acylindric plug which is arranged to turn in said bore, an arm which isprovided to the outer end of said plug and arranged to lie in saidcavity with its outer surface flush with the adjacent outer surface ofthe bowl, and with a space between the edge of the arm and the edge ofthe cavity for the insertion of an instrumentality for starting the plugfrom the bore, and a semi cylindric scoop provided to the inner end ofthe plug and placed in the passage of the pipe-stem to scrape the sameby a turning movement of the scoop, substantially as herein describedHENRY M.
